1.4 Connection with PC
The connecting method with the 485PC-IF is available in two-pair wiring and one-pair wiring, which may be
used as follows. As for connection of the 485PC-IF and computer, see the 485PC-IF manual.
● Two-pair wiring is required when :
① The RS-422 device is incorporated in the system configuration.
② A high speed response is required (message waiting time is desired to be less than 70 ms).
③ The on-demand function is used (however, the system configuration must be 1 : 1).
④ Adding to a system already using two-pair wiring.
* See the 485PC-IF manual.
● One-pair wiring is required when :
① Adding to a system already using one-pair wiring.
② The system configuration is standardized to RS-485 devices, and two-pair wiring is not needed.
